5d–4f and 4f–4f emissions in Ln-doped sesquioxide ceramics
Source abstract
Abstract
Abstract In this study, various lanthanide and mixed lanthanide oxides (Ln2O3 with Ln = La, Lu, Lu0.5Gd0.5) powders have been synthesized by a coprecipitation method. The luminescence properties and/or the quenching mechanisms of different dopants (europium, cerium, praseodymium) have been studied. Luminescence mechanisms of Ce:Ln2O3 and Pr:Ln2O3, are closely related to the 5d and 4f energy levels positions of the dopant versus materials bandgap and crossing effect between dopant energy levels. Energy level positions have been analyzed through optical spectroscopy and their effect on the luminescence is presented. Eu:Lu2O3 and Eu:LuGdO3 have also been prepared as transparent ceramics and radioluminescence properties are presented.
